There was a time when I didn’t give much thought to timing. If I felt the nudge to cast a spell or light a candle, I’d go with it. And there’s still value in that intuitive approach. But once I began exploring planetary hours, something shifted. I started noticing a deeper alignment in my spellwork, a kind of quiet harmony between my intention and the energy flowing through the day. It became less about casting whenever I had a spare moment, and more about weaving my magic into the rhythms of the cosmos. Planetary hours aren’t about rigid rules or restrictions. They’re about understanding and choosing to ride the currents of natural energy that are already swirling around us. Once I made that shift, my spellwork became more resonant, almost as if I was co-creating with the universe rather than trying to command it.
What Are Planetary Hours?
Planetary hours are a system of timekeeping based on the traditional seven classical planets: the Sun, Moon, Mars, Mercury, Jupiter, Venus and Saturn. Each planet is thought to rule over certain hours of the day and night, infusing them with a unique energetic signature that can influence your spellwork. Rather than a modern clock’s strict sixty-minute division, planetary hours divide daylight and nighttime into twelve equal segments each. This means the length of each planetary hour changes daily depending on how long the sun is above or below the horizon.
This system stems from ancient Babylonian astrology and was adopted and expanded by Hellenistic astrologers, medieval magicians and Renaissance occultists. It’s part of a larger worldview where the movements of celestial bodies are seen as influencing the energetic patterns on Earth. By tuning into those energies, you become part of a long lineage of magical practitioners who observed the sky not just for light, but for wisdom.
How Planetary Hours Work
Each day of the week is associated with a ruling planet, and that planet governs the first hour after sunrise. From there, the hours proceed in a sequence known as the Chaldean Order, which follows the perceived speed of the planets from a geocentric perspective: Saturn (slowest), Jupiter, Mars, Sun, Venus, Mercury, Moon (fastest).
Planetary Days and Their Rulers:
- Sunday: Sun
- Monday: Moon
- Tuesday: Mars
- Wednesday: Mercury
- Thursday: Jupiter
- Friday: Venus
- Saturday: Saturn
So, on a Tuesday (Mars day), the first hour after sunrise is a Mars hour. The next hour follows the Chaldean Order and would be the Sun, then Venus, and so on. This cycle repeats through all twenty-four hours of the day and night. Once you get familiar with the sequence, you’ll start recognising how the day’s energy subtly shifts from hour to hour. It can become a rhythm you intuitively feel, especially when paired with mindfulness or journaling.
Why Use Planetary Hours in Magic?
Using planetary hours in your magical practice is like aligning yourself with the tides of energy already present in the world. Each planet brings with it a set of associations and qualities. When you time your spellwork to match the ruling planet’s energy, you’re essentially giving your spell a natural current to ride. It’s an act of harmonisation rather than effort.
Many witches find that their results improve when they sync their rituals to planetary hours. It adds another layer of purpose and presence to the work. Even if your spell is small or simple, working during the appropriate hour helps you attune to the energy you’re calling in. It’s also a gentle way to build discipline and ritual into your craft, especially if you’re looking to deepen your magical awareness or create more routine around your practice.
Planetary Energies and Magical Correspondences
Sun
Focus: Success, confidence, leadership, fame, clarity, health
Good for: Spells for personal growth, confidence, visibility, and healing. Great for solar magic and anything to do with authority or power.
The Sun represents clarity, vitality and purpose. It burns away confusion and infuses your intentions with courage and visibility. Use Sun hours when you want to shine, whether that’s through confidence in a job interview, launching a project, or stepping into leadership. It’s also perfect for healing magic that boosts physical strength or vitality. Sun magic is empowering and often quite fast-acting, as if it burns right to the heart of the matter.
Moon
Focus: Emotions, intuition, dreams, fertility, home, psychic development
Good for: Divination, dream work, emotional healing, spells related to the home or family, and connecting with your intuition.
The Moon governs the subconscious, inner wisdom, and the ebb and flow of emotional tides. Working in Moon hours can bring gentleness to your magic, making it particularly effective for introspective or protective work. It’s ideal for nurturing yourself, connecting with spirit allies, and tuning into your own intuitive guidance. You may find your divination sessions more accurate or your dreams more vivid when timed with the Moon.
Mars
Focus: Action, courage, protection, energy, strength, conflict
Good for: Protection spells, breaking hexes, courage boosts, physical strength, and confronting conflict or fear head-on.
Mars is the planet of raw action and unshakable will. It’s perfect for when you need to cut cords, draw a boundary, or energise your willpower. This is high-octane energy, so aim it with precision. Mars hours are excellent for initiating change, sparking motivation, or overcoming fear. If you need a magical push to get through something hard, Mars is your ally. Just be mindful to direct this force wisely—it’s best wielded with clarity, not in anger.
Mercury
Focus: Communication, travel, intellect, technology, contracts, trickery
Good for: Job applications, interviews, business negotiations, tech issues, studying, learning, and messaging spells.
Mercury moves quickly and adapts easily. It’s ideal for spells that involve information exchange—emails, speeches, writing, or learning. Mercury hours are great for clarity spells before a big conversation, tech-related workings, and making sense of confusing or chaotic thoughts. You can also use this time to sign contracts, troubleshoot issues, or connect with your guides through writing or automatic journaling.
Jupiter
Focus: Expansion, growth, abundance, luck, wisdom, justice
Good for: Abundance spells, career growth, legal matters, luck, and anything that needs a little push toward growth and good fortune.
Jupiter is like the warm hand of fortune, expanding whatever it touches. It’s associated with long-term blessings, spiritual learning and prosperity. Spells performed during Jupiter hours tend to have a graceful, uplifting feel. They’re wonderful for job opportunities, legal wins, and wealth-building. Jupiter is also connected to generosity and fairness, making it ideal for ethical abundance and karmic alignment.
Venus
Focus: Love, beauty, pleasure, relationships, harmony, attraction
Good for: Love spells, glamour magic, reconciliation work, romance, friendships, and creative expression.
Venus rules attraction, connection and artistic expression. This energy is sensual, soft, and emotionally rich. Use Venus hours for beauty rituals, enhancing your charm, mending relationship tensions, or simply bringing more joy and indulgence into your life. Venus also loves pleasure, so if you’re working on body confidence or pleasure-based healing, these hours are perfect.
Saturn
Focus: Discipline, boundaries, structure, protection, endings, wisdom
Good for: Banishing spells, cutting cords, setting boundaries, long-term goals, and ancestral work.
Saturn helps you get serious. This is deep, grounding magic that supports discipline, commitment, and karmic closure. Use Saturn hours to end unhealthy habits, finalise lessons, and set intentions that require sustained effort. Saturn also governs time, so any long-term goal—like weight loss, career building or ancestral healing—benefits from this energy. Saturn’s wisdom is quiet, but deeply transformational.
How to Calculate Planetary Hours
The easiest way to calculate planetary hours is through digital tools. There are plenty of apps and websites that will tell you exactly which planet rules which hour in your location. But if you enjoy a more hands-on approach, here’s how to calculate it manually.
Step One: Find Your Sunrise and Sunset Times
Look up the exact time of sunrise and sunset for your area. These times change daily, so you’ll want to check often if you plan to track planetary hours regularly. This forms the basis for your daylight and nighttime divisions.
Step Two: Divide the Daylight and Nighttime Hours
Take the total number of minutes between sunrise and sunset and divide it by twelve. This gives you the length of each daytime planetary hour. Then do the same with the time between sunset and the next sunrise for the night hours. You’ll now have a list of hour blocks you can assign planetary rulers to.
Step Three: Follow the Chaldean Order
Start with the planet that rules the day for the first hour after sunrise, then assign each following hour according to the Chaldean Order. Once you’ve made one full day’s chart, the pattern becomes easier to follow and predict. Keep a notebook or calendar handy if you prefer not to use digital apps. Over time, you may even start to feel when a certain planet is ruling an hour by tuning into the shift in energy.
Tips for Working with Planetary Hours
Keep It Flexible
You don’t have to be exact down to the minute. Magic is about flow and intention, not rigidity. If you’re within the general planetary window, your spell is still well-supported. It’s more important to be in the right frame of mind than it is to be watching the clock.
Layer Your Timing
When you combine a planetary day and a planetary hour—like doing a love spell on Friday during a Venus hour—you’re doubling the influence of that planet. This makes your magic even more aligned. If you can’t layer both, just choose whichever is more accessible that day. Even a single layer can have a beautiful effect.
Match Tools and Colours
Adding in colours, herbs, crystals and tools associated with the planet you’re working with strengthens the resonance of your spell. Think pink roses and copper for Venus, or amethyst and silver for the Moon. These small details weave a richer magical experience and help anchor your intention more deeply.
Plan Ahead
If you’re a planner, it can be helpful to schedule your spellwork in advance using a planetary hours chart or app. Marking out ideal windows for specific spells can make your practice more intentional and less rushed. Over time, you’ll develop a natural sense for the planetary flow, and it will begin to feel more like second nature than something you have to calculate.
Real Life Examples
- When I needed to have a difficult conversation with someone, I waited for a Mercury hour. I wrote down what I wanted to say and visualised the outcome. When the time came, the conversation was calm, clear, and productive. I walked away feeling understood instead of drained.
- I once anointed a green candle for abundance and lit it during a Jupiter hour on a Thursday. I spoke aloud my intention, focusing on growth and generosity. That month, I landed a new client and received unexpected money from a refund. Now, Thursday Jupiter hours are part of my money spell routine.
- When my dreams felt foggy and I couldn’t remember them, I started journaling during Moon hours before bed and doing short dream rituals. My dreams became more vivid, with clearer symbolism. The Moon helped me reconnect with my subconscious, and it felt like tuning into a quiet conversation within myself.
Common Questions About Planetary Hours
Can I still do magic if the timing doesn’t line up?
Absolutely. Timing is a tool, not a rule. If you feel called to do a spell at a time that doesn’t align with planetary energy, trust your instincts. That intuitive nudge is its own kind of magic.
Do planetary hours work with other astrological timing?
Yes. You can layer planetary hours with moon phases, zodiac signs, or even transits. This makes your magic more detailed and specific. For example, combining a Venus hour with a new moon in Libra can be powerful for intention-setting in relationships.
What if I miss the hour?
It’s not the end of the world. The universe isn’t a ticking clock. Simply wait for the next appropriate window, or go ahead and cast your spell anyway. Your magic is not dependent on perfect conditions—it’s dependent on your will and your heart.
Final Thoughts
Planetary hours have become one of my favourite ways to bring rhythm and reverence into my craft. They help me feel more grounded, more attuned, and more connected to something ancient and wise. Whether you use them every day or just when it feels right, they offer a beautiful framework to support your intentions.
The best way to learn is to start noticing. Track a few planetary hours, see how they feel, and experiment with timing your spells. There’s no wrong way to begin. And you may just find that the universe starts to meet you in ways that feel surprisingly aligned and full of magic.
